Stellar evolution models suggest that neutrino cooling is the dominant source of energy loss for stars near the lower end of the instability strip occupied by the variable pre-white dwarfs. The fraction of the total luminosity contributed by neutrinos increases with increasing mass at every phase of pre-white dwarf evolution. However, at the high-temperature end of the instability strip, neutrinos contribute only a small fraction of the overall luminosity. Recent asteroseismological analysis of light curves of pulsating pre-white dwarfs near the low temperature bound of the instability strip indicate a trend toward higher masses with decreasing temperature for pulsators within the strip. Future measurements of secular changes in the period of the dominant modes in these cool, massive pre-white dwarfs can therefore constrain the neutrino emission taking place in their electron degenerate cores.
